FOUR(ISH) GUIDELINES FOR USING
COMBINING VOWELS

• Word root + suffix
• CV used if the suffix does NOT begin with a vowel
• Example:
– Arthr/o/pathy

• Word root + suffix
• CV NOT used if the suffix begins with a vowel
• Example:
– Hepat/ic

• Word roots + word root
• CV is used even if vowels are present at the junction
• Example:
– Oste/o/athr/itis

• Prefix + Word root
• CV is NOT used
• Example:
– Sub/hepat/ic

Practice (T or F)  if false give the reason WHY…
• 1. There is always prefixes at the beginning of medical terms
• 2. A combining vowel is always used when connecting a word root and a suffix that begins with the letter o.
• 3. A prefix modifies the meaning of the word.
• 4. A combining vowel is used to ease pronunciation.
• 5. I is the most commonly used combining vowel.

• 1. There is always prefixes at the beginning of medical terms
• F
– A medical term may begin with the word root and have no prefix
• 2. A combining vowel is always used when connecting a word root and a suffix that begins with the letter o.
• F
– If the suffix begins with a vowel, the combingin vowel is usually not used
• 3. A prefix modifies the meaning of the word.
• T

• 4. A combining vowel is used to ease pronunciation.
• T
• 5. I is the most commonly used combining vowel.
• F – O is the most commonly used

• 6. The word root is the core of a medical term.
• 7. A combining vowel is used between a prefix and a word root.
• 8. A combining form is a word part.
• 9. A combining vowel is used when connecting a word root and a suffix if the suffix begins with the letter g.

• 6. The word root is the core of a medical term.
• T
• 7. A combining vowel is used between a prefix and a word root.
• 7. F
– A combining vowel is used between two word roots or between a word root and a suffix to ease pronunciation

• 8. A combining form is a word part.
• F
– A combining form is a word root with a combining vowel attached and is not one of the four word parts
